Today it seems we need smartphone apps to remind us to do everything. To sleep, eat, wake up, breathe, and, yes, drink water. This makes sense when you consider that the average human body contains about 60% water. Staying hydrated is absolutely crucial to maintaining a healthy body. But sadly the average person is chronically dehydrated. Since smartphones now help us with everything in our lives,why not help us drink enough water? Of course most people will not need a water app to remind them to drink more water. However, for those that do, there are lots of options. The good news is that most of them are free or incredibly cheap. Some of them are a straightforward water reminder app. These apps will go off at certain intervals in order to remind you to drink water. While others are more sophisticated and will take your weight into account and dictate the correct amount of water you need to drink. There are even others that can track how much water you have taken already. Trying to go on a water diet? The 30 day 1 gallon a day water challenge? Or simply, trying to drink more water? Get an app to help you track and manage this process. Below are my article reviews of the best water tracking apps and gadgets that will help you drink more water.
